Automatically control PWM fan based on temperature?

I have purchased on for my Nano and mounted it.

I know I can turn it on by using

sudo jetson_clocks


sudo sh -c 'echo 255 > /sys/devices/pwm-fan/target_pwm'

But this seems just to turn it on 100% the whole time? Is there any way to have the fan turn on by itself based on temperature of the SoC or heatsink? My Jetson TX2’s fan seems only to turn on when necessary. I don’t want this fan running non stop if I don’t have to.

Actually I found it…
